    Intensity-dependent upconversion efficiencies of Er3+ ions in heavy-metal fluoride glass (1991)

    Notes: The upconversion of infrared radiation to shorter wavelengths by Er3+ ions in heavy-metal fluoride glasses, some doped with Yb3+, has been studied over a wide intensity range and for various excitation wavelengths. The upconversion efficiency measured at room temperature varies linearly or quadratically with intensity and saturates at 100 W/cm2 or higher, depending on emission wavelength. For 4 mol % ErF3 in BaF2/ThF4, the 4I11/2 to 4I15/2 transition is over 10% efficient for 400 W/cm2 of absorbed 1.5-μm power, i.e., for 4I15/2 to 4I13/2 excitation. A rate equation model and Judd–Ofelt analysis of data for the glasses doped with just Er3+ provide an understanding of the upconversion process while yielding values for Er3+ energy-transfer rates and excited-state populations. These results could be used to develop glasses for lasing and as infrared optical detectors.

    Description / Table of Contents: Résumé Entre 1985 et 1992 46 patients avec un cancer épidermoide du canal anal ont été traités prospectivement par un protocole d'irradiation combiné à une chimiothérapie par 5-Fluorouracil et Mitomycin C. Le taux de survie, le taux de survie NED et le taux de contrôle local des tumeurs était de 84%, 71% et 83% à 5 ans. La fonction ano-rectale a été préservée chez 33 des 41 patients (80%). Nous avons observé une toxicité aigue sévère comprenant 3 décés mais une très faible morbidité ultérieure. Le seul facteur pronostic significatif (P=0.06) de contrôle local de la tumeur était le stade T. La survie NED était significativement affectée (P=0.02) par la réduction de la chimiothérapie durant la deuxième cure.
    Notes: Abstract Between 1985 and 1992, 46 patients with epidermoid carcinoma of the anal canal were treated prospectively by a protocol of combined radiation and chemotherapy with 5-Fluorouracil and Mitomycin C. The survival rate, NED-survival rate and local tumour control rate were 84%, 71% and 83% at 5 years. Anorectal function was retained in 33 of 41 patients (80%). We observed severe acute toxicity including three deaths, but very little late morbidity. The only marginally significant prognostic factor (P=0.06) for local tumour control was T-stage. NED-survival was significantly affected (P=0.02) by reduction of chemotherapy during the second course.

    Serumeiweiß-Untersuchungen beim Erysipelas recidivans (1972)

    Description / Table of Contents: Zusammenfassung Verfasser haben im Serum von 50 Patienten mit rezidivierendem Erysipel AST-, Serumeiweiß- und immunelektrophoretische Untersuchungen durchgeführt. Als charakteristisch wurde die Erhöhung der AST-(45 Fälle) und der Beta1-Globulinfraktion (32 Fälle) befunden. Den Anstieg der Alpha1-, Alpha2- und Beta-Globulinfraktionen sowie deren immunelektrophoretischer Repräsentanten (Alpha1-Antitrypsin, Alpha2M-Globulin, Transferrin) lassen die Autoren als eine bei chronisch-entzündlichen Krankheitsprozessen zu beobachtende Erhöhung des Serum-Glykoproteidgehalt auf, halten diese aber für das recidivierende Erysipel als charakteristisch.
    Notes: Summary Antistreptolysin titer (AST), serum protein analysis and immunelectrophoretic studies of the serum have been carried out in 50 patients suffering from erysipelas recidivans. An increase of AST (in 45 cases) and of beta1c globulin (in 32 cases) was found to be caracteristic. The increase of the alpha1, alpha2 and beta globulin fractions, as well as of their immunelectrophoretic representatives (alpha1 antitrypsin, alpha2M globulin, transferrin), is in agreement with literature data and can be explained by the increase of the serum glycoproteid level present in chronic inflammatory processes. They are regarded as characteristic for this disease.

    Description / Table of Contents: Zusammenfassung Es wurden an 27 Patienten mit verschiedenen Dermatosen die vom Streptolysin O auf die Leukocytenmigration entfaltete Wirkung untersucht und jene optimale Konzentration dieses Antigens bestimmt, welche die Zellmigration am wirksamsten hemmt. Die Dosis 0,2 IE/ml Streptolysin O hatte — abgesehen von 2 Fällen — eine ausgesprochene Hemmung der Leukocytenproliferation zur Folge. Ein Zusammenhang zwischen dem Inhibitionsgrad der Migration, d.h. dem Ausmaß der cellulären Immunität, und dem Antistreptolysintiter wurde nicht gefunden.
    Notes: Summary Effect of Streptolysin O on leukocyte migration has been examined in cases of 27 patients suffering from various dermatoses. Determination of the optimal concentration of this antigen inhibiting cell migration most effectively, has been carried out. 0.2 IU/ml Streptolysin O, except for two cases, markedly inhibited proliferation of leukocytes. No relation has been found between the degree of migration inhibition, that is the degree of cellular immunity, and antistreptolysin titre.

    Elektronenmikroskopische Untersuchung der präfascialen Lymphgefäße beim rezidivierenden Erysipel (1973)

    Description / Table of Contents: Zusammenfassung Bei insgesamt 32 Kranken beiderlei Geschlechts im Alter zwischen 17 und 78 Jahren mit stets auf die unteren Extremitäten lokalisiertem, meistens mit Lymphödem einhergehendem rezidivierendem Erysipel wurden vor der Lymphangiographie aus den präfascialen Lymphgefäßen beider Fußrücken Excisionen zwecks elektronenmikroskopischer Untersuchung vorgenommen. Dabei konnten mehrfach normale Verhältnisse registriert werden. Bei Lymphangiektasieund Lymphangitis-Zuständen waren eine partiale Dehiszenz der interendothelialen Junktionen und davon ausgehende größere Erweiterungen zu beobachten. Bei der Lymphangiopathia obliterans bestand zahlenmäßige Verringerung der Muskelzellen. In den Endothelzellen der pathologischen wie auch der normalen Lymphgefäße gelangte das „fine filaments“-System zur Beobachtung. Die Anreicherung der pinocytotischen Bläschen sahen die Autoren vor allem bei Kranken mit Lymphangiektasie und erblicken in ihr ein Zeichen der Läsion des Transportes durch die Endothelzellen und der Insuffizienz der Gefäßwandernährung.
    Notes: Summary An electronmicroscopical study of prefascial lymph vessels from both feet of 32 patients suffering from recurrent erysipelas located in the area of the lower limbs has been carried out before lymphangiography. Most of the patients had lymphedema localized mainly on the feet and legs. Normal conditions have often been observed. In lymphangiectasia and in different lymphangitic states partial separation and cystic dilatation of interendothelial junctions have been observed. The number of muscle cells was decreased in lymphangiopathia obliterans. Systems of "fine filaments" could be seen in the endothelial cells of both pathological and normal lymph vessels. Increase of pinocytotic vesicles could be demonstrated primarily in lymphangiectasia. It is supposed to be a symptom related to the deficient nutritive function of the lymph vessel wall.
